I started to create the MathQuiz and it is working good as per the provide codes. I was also able to add 'Percentage Correct Answers' and some other details.I have added a new form with some buttons and that is working as well, just simple stuff and all good fun playing with it.
But here is my challenge:When 1 or more answers are incorrect the program is opening a new form (similar to the main form) and it shows the equations again. I did that with "Correcting.lblLADD.Text = addend1", etc. in then main form. In the form 'Correcting' = Form3.Designer.vb I have tried to get the Text into a Number but nothing works for me. Also Tried to make addend1 in Form1 Public but the value does not appear in Form3. Form3 has also a Private addend1 as Integer.Even if I give addend1 in Form3 a value Form3 does not calculate.Maybe it does but I can get it to work. I have tried to get a MessageBox to show up when the answer in Form3 is correct but the MessageBox does not work either.
I'm storing a multi-line text file (in .dir format) in the directory the user chooses, and what I need to do, is when they import it (which my program can already do) I need it to find the end of the file (line) and then read that line, that line will be a number which corresponds with a number system. Basically, the file looks like this

I have beginner skills using VB (am using the Express edition to learn). I would like to know how to set up a conditional statement in a Windows Form (WF) app that would check if a specific command line has been passed by another separate app that launchesthe Windows Form app using command lines, and if not passed, then the Windows Form app would shut down (exit, close).So far, I can use:
For Each s As String In My.Application.CommandLineArgs
If s <> "xyz" Then
Me.Close()

Me.pass = Conversions.ToString(CDbl((((Conversions.ToDouble((4 & 3)) - Conversions.ToDouble(4)) + (Conversions.ToDouble(2) * Conversions.ToDouble(1))) / Conversions.ToDouble(2))))

I am a newbie when it comes to programming. Right now I am trying to create a program that will read in a .txt file that consists of different integers on each line. For example, the .txt file looks something like this:
[Code]...
I loaded a text file to a text box, and I want the program to find a certain line containing only the strings I specify. But the text file will likely contain many of them, so I want it to pause scanning at the first line I'm looking for until I tell it to continue, then the second line, and so on. So the questions are:
1. What's the method for finding the exact line I want in a text file?
2. How do you start, pause, and resume scanning a text file line by line?
I need to find certain text in a text file or text box and copy next line. How can I do it?

i'm working on a system that upgrades a basic version to a proversion but i have a payment gateway . it generates a code in an SQL DB.now i have a form in VB that has a textbox and a button how can i let VB connect to my SQL DB receive the code and then check if that code is correct and if its correct download silence the pro file. from an url.
View 7 RepliesI have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)
[code]....
The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)
what i need to do is open a txt file, read line by line, decode each line into an array and display. Now all works ok apart from one line.

I am amateur programmer.so far, I can use Visual Basic .Net only. That is all I know!!How can I refer to a MessageBox?or how can I Programatically handle a MessageBox after it is displayed?I need to close a MessageBox after certain time if no response from the user.
View 3 RepliesI'm using MessageBox to give some information to the user, but when such a box pops up, I want it to block access to the main window. So, until the user has clicked "OK", they should not be able to click (or even focus on) the window that's below it.
Does anybody know how to do this? I've noticed that MessageBox has very few functions, so maybe I'll even have to use a different object for this.
I have this
Dim st1 As String = sref.ConfirmLogin() 'A WCF method call.
Windows.Forms.MessageBox.Show(st1 & Environment.NewLine & "blue", "Result")
What is interesting about this is that there is no new line in the messagebox, and "blue" doesn't show up. If I reverse the order, then all is well. If I turn st1 into some other random string, all is well. However, as long as st1 is a string that comes from the WCF call, everything after st1 in the MessageBox is ignored.So what is coming from the WCF call?
The lines are these:
resp.GetResponseStream.Read(buff, 0, 99)
Return Encoding.ASCII.GetString(buff)
resp is a WebResponse object, though that shouldn't matter, as the key is that I take a stream, move it to a buffer, then turn that buffer into a string. What is it about the string that is alterning the way the string is displayed.If I highlight the "st1 & "Blue"" part, and press Shift+F9, it is all there. What I do notice is that there is a significant space beyond the end of st1 and before the Blue. Trim doesn't get rid of this space. My theory is that what is there is a series of Null bytes, and MessageBox is interpreting that as the end of the string and terminating the display at that point, even though it shouldn't really be terminated there. That's especially interesting because I can add in an Environment.NewLine, which would normally add a new line, but even that gets ignored.
I have a Main and a Secondary form. I want that the secondary form appear if the no button in the messagebox is pressed (but the main main don't). Only if I press the yes button or when closing the secondary form the Main must appear. How can I do that?

View 7 RepliesI want to add a yes/no function to a message box (Are you sure you want to exit?) in InfoPath 2007. If the user clicks 'Yes' the InfoPath form closes, if no, then the user is taken back to the form. From what I have read this will not happen in InfoPath. So, I added a new windows form that has the Yes/No buttons.
For the 'No' button, I have (me.close) which closes the windows form and the user is left with the InfoPath form. when the user clicks 'Yes' meaning they want to close the windows form AND the InfoPath form. Below is my code so far.
Imports Microsoft.Office.InfoPath
Imports System
Imports System.Xml

I have a strange problem here. In my code, variable b string, has the value "Test Test Test". This value we can see while debugging the variable as well as in the text visualizer.Now the problem is, if I show the same string using Messagebox, the value is just "Test". What can I do here to get the complete value.
I am converting from an ebcdic encoded bytes to corresponding utf8 string and doing the above operation. Any thoughts. below is my sample code.
